镉及其化合物广泛用于电镀、合金制造、焊料、颜料、电池和半导体元件等工业生产。它常与铅、锌矿共生,故自人类开采铅锌矿以来,就存在镉对环境的污染问题,近年来随着工农业生产迅速发展,它对环境污染愈益严重,成为公害之一。职业性镉中毒有文献报道,结论比较肯定。对镉的 Cadmium and its compounds are widely used in electroplating, alloy manufacturing, solders, pigments, batteries and semiconductor components such as industrial production.
